ixgbe_free_q_vector(9)

✨ ixgbe_free_q_vector — the cleanup queen 👑💅

Okay bestie, so this is a page from the Kernel API Manual about ixgbe_free_q_vector, and it's literally the "bye bye, memory" function for one specific interrupt vector. Let's get into it 🫶

---

🌸 NAME 🌸

ixgbe_free_q_vector — frees the memory that was allocated for one specific interrupt vector 💖

---

✨ SYNOPSIS ✨

void ixgbe_free_q_vector (struct ixgbe_adapter *adapter , int v_idx );

---

🎀 ARGUMENTS 🎀

• adapter — the board's private structure that you're initializing, bestie 🦋
• v_idx — the index of the vector that's getting freed, no cap 💅

---

💜 DESCRIPTION 💜

So basically this function frees the memory that was allocated to the q_vector. And listen — on top of that, if NAPI is enabled, it also deletes any references to the NAPI struct before it frees the q_vector. Order matters, iykyk 😭🔥

And that's the whole vibe, bestie 💖 This gem lives at ./drivers/net/ethernet/intel/i... and it's serving October 2026 energy, from the ixgbe_free_q_vector(9) era 🎀✨🦋 Periodt.
